Application filed. October 2, 1925.

Heretofore it has been the practice in making articles of this character to form the spacer out of metal stamped from a sheet with the result that there is'much waste. This is the case in making the spacing member shown in U. S. Patent No. 1,541,360, issued. to me and Harry W. Hahn, June 9, 1925.

In making metal corner heads it has been the practice to stamp plastei receiving holes in the strips of metal and then form the strip into the corner head, with the result that the slugs or pieces stamped out of said strips in forming the plaster-receiving holes are wasted, because they were not cut in a predetermined design or form for use.

I have conceived the idea of forming the holes in corner bead strips of special forms in order that the slug or piece stamped out of the sheet can be used to form a spacer for stucco nail, and thus eliminate waste in manufacturing corner beads and also in manuhicturinp,- spacers for stucco nails.

In order to explain my invention, I have shown on the accompanying sheet of drawings a strip of metal formed for corner bead service and a spacer formed out of the slug or piece stamped out of said strip of metal in order to make the plaster-receiving hole. in the drawings illustrating one form or our bodiment of the invention,-

Figure 1 is a perspective view of a strip of metal after being punched and before bein formed into corner head;

Figure 2 is a perspective view of the fin ished corner bead;

Figure 3 is a view of the piece stamped out of the strip, referred to as a slug;

Figure 1 shows the slug after the first action thereon of the dies with nail in position above, ready to be positioned for the next action;

I will now describe the use of this special slug, or piece, 6, stamped out of the strip 1. to form the holes, 2, 3, which become plaster receiv ng holes in the corner bead. As said strip is moved through the proper dies for the punching operation, said slugs fall therefrom in a form to be used, in the formation of a spacer for a ucco or furrino' nail with W 1 a hole, I, therein, as indicated infie'. 3. The slugs are then moved to the press and the first operation folds said slug,- in the 43 ilsllitmml p e 1., sins Oi said slug have the recesses 8, formed therein in the original stampi operation, and for a purpose hereinafter forth The next step in the method of forming the article as shown in 5., is the insertion of a nail, 9, into the hole, '2', hctwcen the sides of the U- shape form, whereupon dies come together on the opposite sides thereof and press said sides around the nail, fern o; the fold into a flat bearing foot, 10, crossi se of the plane of the meetings: sides. The structure: thus formed is of ll -S18E38 with the sides folded toward the head of he nail, or with the nail extending; through the stern portion. of said T-shape, as will be clear item 5 and 6. Attention is called to the fact that this form of fastening means is stronger than the one shown in the patent hereinbeto re referred to, for the reason that there is a bead-like torm around the nail and longitudinally thereof, as at 11, while the bearing foot, 10, is double thickness, pressed together tightly and is transversely of the bead-like form 11, as will be clear. The recesses, 8, 8, in the meeting edges of said structure, receive the wire to be held and when the nail is driven home, the head of the nail bridges said recesses and holds the wire therein, in a manner which will be clearly understood by those "ersed in the art to which this invention appertains.

So far as I am aware, I am the hrs to conceive of the idea or" preventing waste in the formation oi such articles as those described herein by providing a predetermined and specially formed. hole in an article which must be provided with holes in order to perform the function for which it is made, and thus making possible the use of the pieceor slug cut out in forming such hole for mel ing another article, such as a spacer "for a furring or stucco nail. The waste in connection with forming spacers also prevented, for heretofore it has been necessary to stamp out the blanks or sl and waste the portions of the sheet or s ii from which they are stamped. By forming the holes in the corner head, or such other articles as must be provided with holes, so that the piece or slug stamped therefrom wi be usable for another article, it making; no paricular difference as to the form of the hole in the corner bead just so it is sufficient to receive plaster in this case, l have made an important improvement in the art oi: manufacturing corner bead and spacers for stucco or fur-ring nails, and believe that invention is involved in the method, as well as in the improved article itself, and while 1' have shown and described my invention in connection with the manufacture of corner bead and spa for stucco or furring nails, I do not limit the invention to the exact showing made for illustrative and explanatory purposes, except as lmay be limited by the hereto appended claims.
